可持续煤矿矿井水处理与资源化技术综述

Summary of Sustainable Coalmine Water Treatment and Resource Utilization Technology

煤矿开采过程中会产生大量的废弃矿井水,不仅造成水资源的大量浪费,而且还威胁着矿区生态环境。本文综述了我国常见矿井水的常规处理方法,以及将矿井水视为水资源的可持续矿井水水处理与资源化技术,首次提出以“时间维度和空间维度”对矿井水进行全时空处理,并着重阐述了矿井水分级处理、分质利用技术,反渗透浓水处理与资源化技术,煤泥处理与资源化技术,以及重金属回收与利用技术等,对煤矿区矿井水处理与资源化利用具有指导意义。

A large number of abandoned mine water will be produced in the process of coal mining,which not only causes a large amount of waste of water resources,but also threatens the ecological environment of the mining area.This paper summarizes the conventional treatment methods of mine water common seen in our country,and the sustainable treatment and resource utilization technology of mine water,which regards mine water as water resources.It is the first time to put forward the whole space-time treatment of mine wa⁃ter with"time dimension and space dimension",and it focuses on the clarification of classification treatment and quality utilization technology of mine water,reverse osmosis concentrated water treatment and resource utilization technology,coal slime treatment and resource utilization technology,as well as the heavy metal re⁃covery and utilization technology,which have guiding significance for the mine water treatment and resource utilization in the coal mine area.
